This is an ongoing list detailing all films available on the OFFICIAL YouTube Movies channel under 'Free-to-watch'. I refer to the official playlist as reference.

To be updated daily.

Don't worry, Letterboxd team, they're completely legal. Please don't take this down like you did on 27 July 2020 for Full movies on Youtube!

Note: Check the links in the Notes. Use a VPN if you're outside U.S. and can't load the films!

(Yeah, I know, most of these are awful, but sort by rating/popularity and you'll likely see the best ones)

Omission issues documented in YouTube Forums.

Workflow for updating and maintenance (which will be reduced if only YouTube adds the feature to sort videos in playlists alphabetically):

1) Copy link of 'Free to watch' playlist.
2) Backup here. If not working, do it here.
3) Copy all titles from Excel/text file.
4) Alphabetise all the titles in the list.
5) Compare and diff the current and previous lists, and update this Letterboxd list accordingly.
6) Repeat steps 1 to 5 daily.
